Question

the measure of an angle is 15°. what is the measure of its complementary angle?

Explanation:

Step1: Recall complementary angle definition

Complementary angles sum to \(90^\circ\). Let the complementary angle be \(x\). So, \(15^\circ + x = 90^\circ\).

Step2: Solve for \(x\)

Subtract \(15^\circ\) from both sides: \(x = 90^\circ - 15^\circ\).
Calculate: \(x = 75^\circ\).

Answer:

\(75\)
